		 *    `pointStart` and `pointInterval` given in the series options. If the axis

		 *
		 * 2. An array of arrays with 2 values. In this case, the values correspond to
		 *    `x,y`. If the first value is a string, it is applied as the name of the
		 *    point, and the `x` value is inferred.

		 * 3. An array of objects with named values. The following snippet shows only a
		 *    few settings, see the complete options set below. If the total number of
		 *    data points exceeds the series'
		 *    [turboThreshold](#series.cylinder.turboThreshold), this option is not
